Numerical Simulation of 3D Solid-Liquid Two-Phase Turbulence Flow in Axial-Flow Pump Impeller

Abstract

With the use of the RNG k-ε turbulence model and the SIMPLEC algorithm, as well as after the secondary development of the software Fluent, the velocity field and pressure field of a axial flow impeller were numerically simulated in the single-phase (clear water) and the solid-liquid two-phase conditions. The distributions of pressure, velocity and solid concentration in the impeller under the single-phase flow and the solid-liquid two-phase flow conditions were compared. This study has shown that the numerical simulation results are the same as the actual situation.

Numerical Simulation of Fine Particle Solid‐Liquid Two‐Phase Flow in a Centrifugal Pump

“…Due to the complexity of the solid-liquid two-phase flow in the centrifugal pump, the experimental research method is costly and time-consuming, and it is difficult to have a direct understanding of its internal flow state [14]. With the development of computational fluid dynamics, the experts at home and abroad have carried out in-depth research on solid-liquid two-phase flow in centrifugal pump based on the CFD method [15][16][17][18]. Liu et al [19] used CFD technology to simulate the solid-liquid two-phase flow field in a chemical process pump, calculated the flow field in the pump under different particle sizes and concentrations, and studied the distribution of the solid-liquid two-phase flow of the double-suction pump.…”
